End-Crystal PvP Gameplay
Two-Mode AutoCrystal
Spray mode for full-auto crystal spam, Aim mode for precise crosshair placement and breaking. Tune break and place delays, kill on stop, and one-tick break-and-place.
CrystalOptimizer
Predicts crystal deaths on your side so exploded crystals vanish the instant you swing. Marlow engine runs at the packet layer, Client engine hooks attack events.
TriggerBot
Swings the moment an enemy crosses your crosshair. Virtual mode fakes the mouse for a clean look, Direct mode fires attack packets straight at the server.
Anchor & Bed Automation
AutoAnchor drives respawn-anchor and bed detonations for you, juggling glowstone and anchors to charge and set off the explosion at the right moment.
Trap Detection
Flags hostile trap and burrow setups, highlighting unsafe crystal, anchor, and bed positions before you step into them. Keep your distance and control the trade.
Combat HUD & Potion Aids
Arraylist and PotionHUD put your active modules and potion effect timers on screen, so you always know your buffs and loadout at a glance mid-fight.

FAQ

Frequently Asked Questions

Everything you need to know about Marlow Client.

Is Marlow Client really free?
Yes. Marlow Client is fully free and open source with no subscriptions, no locked modules, and no hidden fees. Every feature is available to everyone.
What Minecraft versions can I play crystal PvP on?
The current Marlow Client 26.2 build runs on Fabric 26.2, and the classic Fabric 1.21.11 build is still supported. Install Fabric Loader for your version, drop the JAR into your mods folder, and launch. Both builds are on the downloads page.
How do I open the ClickGUI?
Press Right Shift in-game to open the VapeLite-style ClickGUI. From there you can toggle modules, tweak settings, and set keybinds. Use the #theme command in chat to swap between dark and light skins.
Is Marlow Client safe to download?
Marlow Client is open source, so you can inspect every line of code yourself. The source is public for anyone to audit. As with any file you download, run it through your antivirus first for peace of mind.
What does trap detection do?
Trap detection scans nearby blocks and flags hostile setups — crystal, anchor, and bed traps and burrows — so you can see danger before it detonates. It keeps you a step ahead in every trade.
How does Marlow Client handle anchor and bed fights?
AutoAnchor drives respawn-anchor and bed detonations automatically. Marlow mode triggers charged anchors the instant they cross your crosshair; Packet mode juggles glowstone and anchors to charge and set off the explosion.
Where can I download Marlow Client?
The official Marlow Client download lives only at marlowclient.com. Get the Fabric 26.2 build from the download section or the downloads page; the classic Fabric 1.21.11 build is listed right below it.
